A full sibling population was created, representing two nut cultivars in the University of Missouri (MU) germplasm repository, 'Sparrow' and "Schlessler'. The population consists of 323 seedling full sibs (all derived from the 2008 seed years), plus both parents. Full sibling status was confirmed via paternity exclusion genetic testing on all individuals. This paternity exclusion (PE) work was initiated in 2009 and primarily funded through the University of Missouri Center for Agroforestry (UMCA), in cooperation with the Romero-Severson (JRS) lab at the University of Notre Dame (ND).

Phenotyping of this of this population will be initiated in the spring 2015 and will include:

leafing date

bud burst

pistillate & staminate bloom

season length

anthracnose susceptibility

As circumstances permit, standardized nut characteristics will be assessed using standardized descriptor values developed by IPGRI (1990), including:

% kernel

veination

kernel color

harvest date

shell thickness

Genotyping of this population is ongoing. A set of SSR markers are being used for the entire population, and a subset of trees are also undergoing ddRADTag genotyping.

Please contact us for more information or if you are interested in utilizing this population for research. Genotype and phenotype information will be posted here when publicly available.

A second full-sib population totaling 135 to date, sharing the female parent “Sparrow” with the first population, was started at UM in 2015. The seed parent Sparrow was selected for whole genome resequencing at UC-Davis for a USDA Specialty Crops Research Initiative (SCRI) project headed by David Neale. Data is expected sometime in 2016.
